SCDRDPN

The CICS® transaction specifies the return destination process name (SCDRDPN) in the RTRANSID field of the START command.

When CICS sends this field to IMS, it contains the name of the asynchronous transaction to be scheduled by the CICS mirror transaction when the reply is received.

For unsolicited asynchronous output, the RDPN can be set by MFS to indicate the next message input descriptor (MID) to be used for subsequent replies. If this parameter is received as input by CICS, this parameter should be saved and returned to IMS in the TRANSID (DPN) of the START command.
